【発明の属する技術分野】
本発明は例えば苗載台及び植付爪を備えて連続的に苗植作業及び側条施肥作業を行う田植機に関する。
【0002】
【発明が解決しようとする課題】
従来、多条施肥用ホッパ及び繰出ケースなどを左右方向に並設させることにより、走行車を搭載する運搬用トラック荷台から機外側のホッパなどが突出し易く、施肥機の多条大型化によって走行車を容易に運搬し得ない不具合がある。
【0003】
【課題を解決するための手段】
然るに、本発明は、多条植え用苗載台を有する植付部と、多条施肥用ホッパを有する施肥機を走行車に装設させると共に、走行車の運転席後側に固定させる中央施肥部と、中央施肥部両側に折畳み自在に連結させる左右施肥部と、左右いずれか一側に配設させる送肥ブロワを、前記施肥機に備え、前記の左右施肥部を機体前方に約180度折畳んで運転席の側方で固定させる回動支点軸を中央施肥部よりも機外側に配設してなる田植機において、前記中央施肥部の中央施肥フレームに支点アームを固定し、支点アームに前記回動支点軸を介して回動アームを水平方向に回転自在に連結し、前記左右施肥部の左右施肥フレームに前記回動アームを固定し、左右施肥部を前記回動支点軸に所定高さだけ上昇自在に取付け、作業位置の左右施肥部を上方に持上げ乍ら収納位置に回動させるように構成したもので、下方の本機側部材に対して左右施肥部を上方に回避させて干渉を防止し得、左右施肥部を施肥作業位置または折畳み収納位置に容易に移行させ得、脱着部材または折畳み部材を少なくして左右施肥部の収納作業性向上などを容易に行い得る。また中央施肥部外側に回動支点軸を設けることによって収納位置の左右施肥部と走行車中央部の運転席との間の空間を容易に確保し得、左右施肥部折畳み収納時の運転席の作業者居住性向上などを容易に行い得るものである。

BACKGROUND OF THE INVENTION
The present invention relates to a rice transplanter that includes, for example, a seedling stage and a planting claw and performs seedling planting work and lateral strip fertilization work continuously.
[0002]
[Problems to be solved by the invention]
Conventionally, multiple hopper fertilizer hoppers and feeding cases are arranged side by side in the left-right direction, making it easier for hoppers on the outside of the machine to protrude from the truck bed for transporting vehicles, and for traveling vehicles by increasing the number of fertilizer machines. There is a problem that cannot be transported easily.
[0003]
[Means for Solving the Problems]
However, the present invention provides a central fertilizer in which a traveling vehicle having a planting portion having a multi-row planting stand and a fertilizer machine having a multi-row fertilizer hopper is fixed to the rear side of the driver's seat of the traveling vehicle. The fertilizer is provided with a left and right fertilizer that is foldably connected to both sides of the central fertilizer and a fertilizer feeding blower that is disposed on either the left or right side, and the left and right fertilizer is approximately 180 degrees forward of the fuselage. In a rice transplanter in which a pivoting fulcrum shaft that is folded and fixed on the side of the driver's seat is arranged outside the central fertilizer, the fulcrum arm is fixed to the central fertilization frame of the central fertilizer. The rotating arm is connected to the left and right fertilizers on the left and right fertilizing frames, and the left and right fertilizers are fixed to the rotating fulcrum shaft.
